Newly registered tracks of Raccoon dogs (Nyctereutes procyonoides) indicate the presence of resident population in the region of Bolata dere (NE Bulgaria)

The Raccoon dog (Nyctereutes procyonoides Gray, 1834) is an invasive species which was first recorded for the Bulgarian fauna in 1968. To date, data concerning the distribution of the species in Bulgaria are rather scarce and often provided by non specialists (mostly local fishermen and hunters). The present note includes information concerning the presence of Raccoon dogs in the region of Bolata dere (NE Bulgaria). Faeces and footprints were found in the springs of 2014 and 2015. Apparently, the predators are resident inhabitants of the site, so that particular population could be used for field surveys on the biology of the Raccoon dogs in Bulgaria.
